Glyphochloa henryi
HABIT Annual; caespitose. Culms erect; 50–90 cm long; 5–6 -noded. Culm-nodes swollen; glabrous. Leaf-sheaths 4–5.6 cm long. Ligule an eciliate membrane. Leaf-blade base truncate. Leaf-blades 7–15 cm long; 4–8 mm wide; dark green and light green; discolorous with last colour beneath. Leaf-blade venation with 7–8 secondary veins. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence composed of racemes; terminal and axillary. Peduncle pilose above.
Racemes 1; single; unilateral; 5–9 cm long. Rhachis fragile at the nodes; subcylindrical and excavated; ciliate on margins. Spikelet packing abaxial. Rhachis internodes inflated; 3 mm long. Rhachis internode tip transverse; crateriform.
Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels fused to internode; united wholly; flattened; 3 mm long.
STERILE SPIKELETS Companion sterile spikelets well-developed; bisexual; ovate; 6 mm long; longer than fertile; deciduous with the fertile. Companion sterile spikelet glumes coriaceous; winged on keels; caudate; awned; one glume awned; with 6 mm long awn. Companion sterile spikelet lemmas 2; exserted from glumes; 3 mm long.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus glabrous; base truncate; with central peg; inserted.
GLUMES Glumes dissimilar; reaching apex of florets; firmer than fertile lemma. Lower glume oblong; 0.5 length of spikelet; indurate; 2-keeled; keeled laterally. Lower glume lateral veins ribbed (8–9 ribs below transverse ridge). Lower glume surface rugose (1 ridge near base); glabrous. Upper glume oblong; 3 mm long; membranous; 3 -veined. Upper glume surface pubescent; hairy below.
FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret lanceolate; 3 mm long; hyaline; 2 -veined; ciliolate on margins. Palea of lower sterile floret 3 mm long. Fertile lemma ovate; 3 mm long; hyaline; without keel; 1 -veined. Lemma surface pilose; hairy above. Palea ovate; 2 mm long; hyaline.
FLOWER Anthers 3; 1–2 mm long.
DISTRIBUTION Asia-tropical: India.
